record-strip feed mechanism7 which locking device is furnished with adriving or operating mechanism receiving motion from some convenientmember of the machine, and an interponent or controlling membercontrolled from thc record-strip to render the driving member of thelocking device operative or inoperative on the record-stri p feed asrequired.

It is not considered necessary to give here any details of the mechanismof the keyboard composing machine for producing the repeat signal; suchmachines are Well lrnown and an example thereof is disclosed in thepatent to John Sellers Bancroft and Maui-itz C. I-ndahl, No. QHAO, datedDecember 28th, 1909. An additional or special signalproducing element orpunch can be f ittcd on the machine, or in order that existing machinesmay `be readily-adapted to produce the required signal the repeat signalcan be composed of two signal components which together have nothitherto represented any symbol or the like but either of Which can beor has been hitherto used in conjunction with other components for acharacter or like signal. The mechanism of the present invention is socontrived that when two existing components are employed thepresentation in the casting machine of either component separately or inconjunction with a component not concerned with the present invention,will not operate on the mechanism for interrupting the record strip feedon the casting machine. such mechanism bcing only operative when the twocomponents are presented together.

In the best ltnon'n .'ommercial machines, the signals in therecord-strip are usually perforations which aclV in conjunction with airconduits of a pneumatic s vslcm to operatc the die case or matrixpositioning mechanism of the casting machine. The recordstrip is fedthrough the machine intermittcntl \Y by mechanism operated in timedrelation with the casting mechanism. The mechanism for feeding` thestrip generali)IY comprises a ratchet and pau'l nn-c'lianism whichrotates pin wheels adapted to engage feed holes in the margins of therecordstrip. and the shaft of these pin wheels is rotated step h v stepto present the perforations of the successive signals to a series of airconduits bv which thc die-case positioning mechanisms are controlled.The drivingl paul of the feed mechanism is operated in timed relation tothe casting. and between the pawl and the driving meclianism there isinterposed a vielding coupling so as to avoid damage to the mechanism`should the opera.- tion of the feed mechanism be interfered with.

In carrying out the present invention as applied to an automatic f vpecasting machine as above described. there is mounted contiguous to therecord-strip driving mechanism, a pavvl and ratchet driven notched diskor cam member adapted to operate upon an arm which, when so operatedupon, engages and holds the strip-feed ratchet Wheel; and the drivingpawl for the disk is onl)Y rendered operative to effect the rotation ofthe disk the rer'luired degree blv the repeat signal which acts upon apawl-posilioning member or motor.

The mechanism illustrated with which the pre-ent invention is shownembodied responds in general with that set forth in the patent to JohnSellers Bancroft, No. 625.998 previouslv mentioned. and particularlv asto the paper feeding mechanism lo the improvements thereon shown forexample, in the patents to John Sellers Bancroft,y No. 674,362 dated Mar21st. 1901. and No. 700.289. dated Mav 20th, 1902. to which patentsreference can be had for a detailed deserintion of the mechanism and itsoperation. Tt is sufficient for present purposes to point out some ofthe parts of the casting machine for identification purposes and lorefer to the parts cooperating and co-acting with the mechanism Which ismore particularl)Y a part of the present invention. For example. in thecasting machine shown in Fie'. l it will he suflicient to call attentionto the metal pot 7 supported by the frame 8 capahle of being swung onthe pivot screw il and of being elevated (as shown) or depressed lrvrotating the said screw 9 h v means of-the handle 10; to the flexiblegas conduits ll for leading gas to the burners under the pot 7 and tothe chimneyy l2 for conducting off the products of combustion of thegas: to the pump operating levers lf3. the pump piston spring I4. thepump body spring I5. the mold 16. the mold blade operating rod 17. thematrix carrier 1S. thc die case positioning mechanism represented b vthe jaw or tong 171, the bridge 1D and the centering pin micrometeradjustment screws Q0. the centering pin lever 21, the record strip Q2and the feeding mechanism frame 221. parts of which feeding meel-1anismare more particularly shown in Figs. 2. 3 and 4. It will. ofcourse. beunderstood ln' one skilled in the art that the various mechanisms of themachine sei forth cooperate-to produce east tjpe, in accordance with thelill) signals recorded inV the perforated strip, which strip is,ordinarily fed aiong intermittently andpresents a new Vor a repeatedsignel for each-casting. The'present invention contemplates:mechanismfor rendering the feed mechanism inactive,veherebj-Y one signal is heldVpresented While Vthe other mechanisms continue to operate and thus castrepeatedly the particular type represented by the signal. The means forcausing Such ternporary suspension of the feed under control of a signalWill now be described.

The usual toothed Wheelj23 ofthe paper feed device is mounted upon theshaft 24 of the feed pin Wheels 25; YThe driving pawl 2G is mounted on aring 2? which receives an oecillatin motion from a rocking arm 28through linke- 29 and 30 and a resilient coupling 3l. A holding pawl 32for the Wheel 23 is operated through the link 30. The interpretingmechanism including the air har for the record strip is provided with aseries of air ducts or conduits leading to gages for the die casepositioning mechanism, and between which ducts and an air supply bar orchamber the record strip 22 passes.

ln embodying the present invention in a machine auch as above referredto, advantage is taken of the holding pavvl 32, which is employed to actas the feed locking inember pro er, under the Vcontrol of the mechanismo the present invention. In passing it is to he noted that in commercialmachines such referred to, this holding paivl has' been employed undercertain conditions to lock the paper feed; when sorts or single typeshave been cast and when the machine ie not controlled by a record striprepresenting a piece of composition, it has been'usual to place in theinterpreting mechanism a piece of material perforated for a singlesignal so thatithe die holder will he maintained in :meurateV positionby the positioning mech- 43 fanism. In such cases theV record-strip feedtween the feed strokes of the pawl 26 untilV the repeat signal ispresented.

Mounted upon an extension or arm of the frame A36 is a notched disk orcom 37 which mayI have four notches as shown in Fig. 2, or one notch asshown in Fig. or two asfshown in Fig. 6, in accordance with thepredetermined number ofY caste which each repeat signal is intended todenote. ,When one orY other of the notches 3'? is'rover a projection Y39on the pawl 32 the latter is free to respond normally tothe actionof-its driving mechanism 30, 31,' hut when the normal surface of thedisk 37 is over the projection 39 the paw] 32, as will be seen in Fig.2', is locked in engagement; with the Wheel 23, and its drivingmechanism operates without moving the pawl, and such action is permittedby the resiiient coupling or spring box 3i.

Mounted on the shaft 40 of the disk 3T is a ratchet Wheel 41 which isarranged-to be rotated by a pan-'l 42 pivotally carried on one endV of alever 43 which is loosely mounted on the shaft 40.

The other'jend of the lever 43 is connected by a link 44V with therocking arm'S' fromY which it receives motion to operate the pawi 42 torotate step b v sten the disk 37.V

When Vthe machine is casting ordinary composition and the repeat signalhas not heen presented, the disk 37 is in the position shown in Fig. 3,with a notch 38, over the pawl 32 and mechanism is provided o v whichthe driving pawl 42 for the wheel 4l is prevented from engafring theteeth of the wheel so that the disr 37 is stationary. Conveniently thismechanism comprises a bell crank iever pivotally mounted at 46 on thelever 43 and having one end engaging one end of the paWl 42 or ashoulder thereon. Beneath this pavvl engaging arm of the lever 45 is astop 47 carried by the machine frame and adapted to en age the arm anddisengage the pawl 42 om the Wheel 41.. The lever 45 is so mounted thatit remains in the position it is placed in by the stop 47 until actedupon by another meinber which will he the interponent or operatingmembercontrolled by the repeat signal.

hns, during normal composition, the pawls 26 and 32 control through thedriving mechanism 28, 3l, 29, 30 the feed of the strip, and although themembers 44 and 43 are being operated to rotate the Wheel 41 this isrendered ineffective on the wheel by reason of the action of the stop 47on Vthe pawl engaging lever 45.

:For rendering the repeat signal operative, on the r'nechanismV 37, 45n'lechanismv is provided in accordance with this invention for movingthe lever 45 from the osition in which it is placed by the stop 47 intoa positiori'in which it will turn the paivl so that it Will engage anddrive the Wheel 4l.

In the present embodiment of the invention, the interponent 48 whichact-s upon the lever 45 is controlled by a repeat signal consisting oftwo cxistin components which if presented sin ly or cit er'of them incompany with anot er component will not operate the interponent 48, asthe mechanism is so contrived that it requiresE the simnltaneouspresentation of the tivo components of the repeat signal to operate theinterponen-t 4S. Y

The interpellent 48 is connected to a piston 49 located in a cylinder50, one end of which, through a conduit 51, communicates with a valvechamber 52 in which there is a valve opening 53 normally closed by avalve 54. Beyond the valve chamber is a chamber 55 in which is located apiston 56 the rod of which projects through the wall between chambersand 55 and is connected to the valve 54. The interponent 48 is returnedand piston 49 is held normally against the inner end of the cylinder bya spring 57, and the valve 54 is normally held against its seat by aspring 58.

Leading into the valve chamber is a conduit 59, the air supply to whichis controlled at the air bar 33 by one component of the repeat signal,and leading into the chamber 55 behind the piston 56, is a conduit G0the air supply to which is controlled at the air bar 33 by the othercomponent of the repeat signal.

When the two components of the repeat signal are presented, air passingthrough the conduit 60 moves the piston 56 forward, and the valve 54 ismoved from its seating. At the same time air enters the valve chainber52 by the conduit 59, and passing through the valve opening travelsthrough conduit 51 in to the cylinder 50, pushing the piston 49 and withit the interponent 48 outward.

The interponent 48 is moved to its outer position each time the signalis repeated and strikes the free arm of the bell crank when the latterreaches the end of its upward stroke which is the idle stroke of thepawl 42 so that the bell crank 45 is rocked by the member 48 to more thepaw] into position to engage the teeth ot.' the wheel 4l. The upperdotted line position of the lever 45 and pawl 42, as shown in Fig. 2 isthe same relatively to the lever 43 as the position shown in full lines.An advance of the interponent 48 when the parts are in the dottedposition causes the tilting of the lever 45 and the engagement of thepaWl 42 with the teeth of the Wheel 41, this engagement continuing untilthe lever 45 strikes against the adjustable stop 47.

The wheel 41 is provided with twenty teeth, and when driven by thepavvl. 42 is moved the distance of one tooth at each operation, and cachcomplete stroke of the arm 28 represents a casting.

In the example shown in Fig. 2 the disk 37 has four notches so that eachpresentation of the repeat signal effects the arrest of the record-stripfor five castings.

On the first stroke of the arm 43 after the repeat signal has beenpresented, the disk will be turned the distance of one tooth of thewheel 41 which will bring the shoulder of the notch into contact withthe projection 39 of the holding awl 32, and this pawl will be lockeduntil, by the step by step movement of the wheel 41, the next notch inthe disk l37 comes over the projection 39 which will be when five castshave been made from a particular matrix, the signal for the positioningof which was presented by the record-strip simultaneously with therepeat signal. Should the next signal presented be a repeat signal thecycle above described will be repeated. When the repeat signal iswithdrawn the piston 49 and interponent 48 are returned by the spring 57and air is allowed to escape from the cylinder 50 by the conduits 51 and61.

With a disk having four notches five successive casts can be representedby one signal. Should a greater number of casts than tive be desiredfrom one signal, a disk having a different number of notches may beemployed; for example, with the disk with two notches shown in Fig. 6ten casts will be represented by one signal, and with a disk having onenotch shown in Fig. 5, one signal will produce twenty casts.

In order to facilitate the changing of these disks there are mountedupon the face of the wheel 41 two pins 62 which pass through openings inthe disk and support it, and a ring 63 is placed in front of the diskand the whole detachably secured by a nut 64.

Should the repeat signal comprise or consist of a special perforationwhich is not employed alone or in combination with others to represent acharacter, etc., then the interponent Would be projected by the air fromthe conduit controlled by that per- 100 foration, and this conduit couldopen into the cylinder behind the piston 49, the valve 54 and piston 56being unnecessary.
